To all whomc't may concern Be it known that I, JAGENBERGQa citizen ofthe Empire of Germany, residing at Dusseldorf, Germany, have inventednewand useful Improvements in Machines for Making and Charging Paper Boxes,of which the following is a specification.

This invention relates to a machine for making. paper boxes, andforfilling said boxes with articles such as butter, soap or cigaretteswrapped up in paper. The machine forms the cutout paper blanks intoboxes, into which the inwrapped articles are automatically pushed, afterwhich the boxes are closed.

With this machine the advantage is obtained, that without any manuallabor, say forty or more boxes may be produced, charged and closed in asingle minute, during which operation it is merely necessary to feed thearticles to the machine.

In the accompanying drawing: Figure 1 is a plan of a machine embodyingmy invention; Fig. 2 a longitudinal section on line A, B, Fig. 1, Fig. 3a cross section on line C, D, Fig. -1,-and :Fig. '4. a cross section online E, F, Fig. 1.

The cardboard blanks, slitted in known manner are arranged in a stack 1,and rest upon a feed-apron 3 that runs over rollers 2,

to which intermittent motion is imparted, so

that the bottom blank is drawn off the stack. This movement. :isimparted'to the apron by means ofa toothed sector 4, which engages apinion 5 fast onone of the rollershafts, and which is so actuated by arm5, rod 6, and elbow lever 7 having cam roller 8, from asuitable cam,-that no movement is transmitted to the rollers, during the return movementof the sector. The segrega'tedblank is'drawn between a pair of rollers10, and is thence delivered toendless feed chainsll, running'oversprocket wheels- 12, 13, and actuated by a toothed sector 14 whichengages a pinion 16 fast on the shaft of wheel 13. Sector 14, is-so.actuated from cam 101, by'rod 17 and lever 18 having cam roller 19, thatno movement istransmitted to -shaft 15, during the return movement ofsector 14. Feed chains 111,c0n-' vey the blank to a table 21, where itwill come to rest for a s'hortperiod, owingzto'the arrest of the chains.During =this:t1me the blank is provided, with an adhesive, 'by means ofa plunger '22, fast on -=a slide 23 which 'ismovable along'a rail 24:,and'isreiece 32 which is vertical ciprocated by rod 25, angle lever 26,link 27, and rod 28 which carries a roller 30, engaging cam 29. Rail 24is supported by two rods 31, which are slidably mounted, and areconnected at their lowerends to a crossreciprocated by rod33, and anglelever 34. carrying a roller 35, that engages cam disk 36. .Slide 23together with plunger 22, is-moved sidewise by rod 25, and is then :bythe depression of rods 31, lowered upon a rotating gluing roller 37after which it is again raised, moved .inwardly over table 21, andlowered upon the blank supported thereon, so that the latter is providedwith the adhesive at the places desired. ,After-thisoperation, the blankis:by.chains 11, moved upon a second table composed of a central plateorsection 38, and a pair of end plates or sections 39. The latter are byarms 40 secured to a slidable hollow post 41, which is reciprocated byrod 42, .having roller 43, that engages cam disk 4:41. The central tablesection 38 is fast on apost slidable within the bore of post 41, andsupported by a spring 46. A

pin 47 on post 45,-engaging a slot of post 41 prevents spring 46 fromelevating plate 38, above the level ofplates 39. When the blank :isdelivered to plates :38, 39 such platcsare raised,,to.press theblankagainst abeam or core 48, located. above the central plate 38. Inthis way the further rise of plate 38 is checked, while plates 39 willmove upward along the sides of the core, so as :to foldithose parts ofthe blank which are supported bythe side plates39, against the coresides. Arms 49 carrying plates 50 will now swing-upward, soas to foldthose parts .of :,the blank that project above the core against theupper side of the latter. Arms 49 are fBiSI-zOIlsShZtfiiS51,Garry1ng.gear

wheels .52, which are engaged by racks 53.

The latter-are provided with an arm 5.4 mounted-upon a rod 55, having aroller57 thatiengages cam disk 56, the forked end 58 of 'the rodstraddling the shaft 59 of the cam :disk. A- f-ter the arms haveeffected their folding operation, the plates .50 are retracted, andimmediately thereafter, a

plunger GOcarried by an arm '20 is lowered, V,

so-as 'to press the top of the blank against the upper .side ofthe core,and thus cause the overlapping-blank edges to be; gluedtogetherybyineans of the adhesive. Arm 20 is fast onia :slidable rod 61having a lower forked .end -62 "which straddles shaft .59,

while a roller 64 of the rod engages cam disk 29.

Four cores 48 are provided which are mounted in star-shape uponarotatable shaft 98, having rollers 65 that engage a cam disk 66, whichcauses the shaft to be intermittently rotated through an angle of 90.When the blank of any one core is glued by plunger 60, shaft 98 isturned 90, so that the next core arrivesover plate 38 (which hasmeanwhile descended together with plates 39), so as to be in positionfor .the folding of the succeeding blank, while the old blank is carriedto a further folding device. This last named device is composed of twoplates 68 secured to arms 67 that are mounted on shafts 69, and areswung upward by intergeared wheels 70 mounted on such shafts. One of thewheels 70 is engaged by a rack 71, which is actuated by rod 72 and anglelever 73 having roller 74, that engages cam 101. When plates 68 aresimultaneously swung upward and inward, they strikethe vertical parts ofthe blank that project beyond the end of the core, the blank being hereslitted at its edges, to form four separate flaps. The two verticallypositioned flaps are thus turned inwardly and made to overlap eachother, over the end of the core. A, vertically disposed plate 76 securedto an arm 75 is then lowered along the end of the core, so as to foldthe upper flap upon the side flaps, after plates 68 have receded. Arm 75is carried by a slidable rod 77, which is operated by rod 78 and anangle lever 79 having a roller 80, that engages cam disk 81. When plate76 has arrived at its lowermost position, a further plate 82 begins torise and to engage the lower flap of the, blank, which during therecession of plate 76, is by plate 82 folded against the threepreviously folded flaps.

Plate 82 is fast on an arm 84 mounted on shaft 83. This shaft furthercarries a lever 85 connected to a rod 86, which with its lower forkedend88 straddles shaft 87, while a roller 89 ontherod engages a cam disk 95fast on said shaft. Thus plate 82 is raised by the rotation of the camdisk, and is firmly pressed against the end of core 48, so that thebottom flap which is provided with the adhesive is glued to the topflap, whereby a box with a closed bottom will be now mounted on thecore. After plate 82 has receded, shaft 98 is again turned 90, so thatthe core with the box is presented to a plunger 90, which imparts to thebottom flaps an additional pressure. Plunger 90 is carried by an anglelever 91, which by rod 92 is connected to an angle lever 93 havingroller 94 that engages a suitable cam disk. Next shaft 98 is againturned 90 so that the core together with the box will be swungunderneath a plate 96, which is lowered upon the core and againcompresses the 1011- gitudinal seam. Plate 96 isfast on an arm 97, of aslidable rod 98, which with its lower forked end 99 straddles shaft 87,and carries a roller 100 that engages cam 101. After plate 96 has beenraised, a stripper 102 engages the end of the box and shoves the latteroff core 48, the stripper moving alonga groove 103, and being rotatablysecured to a slide 105 moving in guide 104. A lever 106 is connected tostripper 102, which by link 107 isconnected to an elbow lever 108.

off the core. In this way the 'box is pro.- ected with its closed endinto a casing 115 which is located directly opposite core 48, and 1smounted on a turnin table 116.

This table is furnished with four of said casings and is fitted to avertical shaft 117, which is intermittently rotated through 90, by meansof a cycle of rollers 118 engaging a cam disk 119. After the box hasbeen pushed into the facing casing 115, the latter is turned 90 in thedirection of the arrow Fig; 1, such movement being accompanied by asimultaneous turning of core 48, so

that, at each period of rest, a casing 115 will be opposed to a core 48.By the turning of the casing, the box arrives opposite means for slidinga charge into the box, the goods comprising this charge being carried tothe machine by means of a conveyer feed belt 111. The foremost articlestrikes an abutment or wall 120, so that the belt will continue to moveunderneath it. Then a plate 121 which is secured to a slidable rod 122is so moved, that the article is pushed sidewise away from the belt.Plate 121 is furnished with a rearward extension 123, which will becomeengaged by the next article carried by conveyer 111. Rod 122 is by link124 connected to an angle lever 125, which'by link 126 is connected to asliding rod 127 having a fork 129 that straddles a shaft '59, while aroller 130 of the fork, en-

gages a cam disk 12 fast on the shaft.

m caw advanced, to push ,the article out of the-container and .into thebox; Plate 142 is .se-

cured to a slidable rod 132, that engages a leyer is guide 133, the rearend of therod bein by rod 134 oined to an angle lever 135. This inked toa rod 136, having a fork 137 that straddles shaft 59, and a roller 138,that engages a cam disk 139 fast on said shaft. During the introductionof the charge into the box, the wings 14.0 are swung outward, andwillthus bear against the inner sides ofthe oppositely positioned flapsof the box cover, so as to bend them somewhat outwardly, and permit thefree entry of the charge into the box. Plate 142 is then retracted,while a plate 144, is lowered from above to fold down anl close theupper cover flap. Plate 144 is carried by an arm 143 of a slidable rod145,having fork 146 that straddles shaft 59, and a roller 147 engaging acam 148 carried by said shaft. Shortly before plate 144 is again raised,a side plate 150 secured to an arm 149 is swung forward, so as to engageone of the side flaps of the box cover and turn the same inward againstthe folded top flap. Arm 149 is carried by a rotary shaft 151, on whichis mounted a cog wheel 152, engaged by a rack 153. This rack is providedwith a fork 154 that straddles shaft 87, and carries a roller 155engaging a cam mounted on said shaft. When arm 149 commences its returnmovement, table 116 will again turn 90, during which movement, that partof the box that projects beyond casing 115, will strike a curvedabutment 157, by means of which the other side flap of the box coverwill be closed. After the completion of this turning movement of thetable, the bottom flap only of the box cover will remainopen. Thisbottom flap will in this position of the table be carried above a plate158 fast on.

the arm 1590f a rotatable shaft 16Q. This shaft carries a toothed wheel16]. engaged by a rack 162 having a fork 163 that straddles shaft 87,and a roller 164 engaging a cam 165 fast on' said shaft. In proximity toplate 158 there is arra nged.a gluingroller 166 turning in a glue pot167 and operated by a belt 168. Above roller 166 thereis free to turn'an arm 169 carrying a dab 170, which impinges against the roller, and isadapted to convey the adhesive to the lower box flap. Arm 169 is securedto a rotatable and slidable shaft 171, carryin a toothed wheel 172, andsupported on the all shaped end 174 of an elbow lever 173. The latter isprovided with a roller 175 engaging a cam 176, while toothedwheel 172engages a rack 177 of a slidable fork 178, that straddles shaft 87. Fork178 carries a roller 1.79 that engages a. suitable cam fast on shaft 87The width of rack 177 is such that in-spite.

' of the displacement of wheel 172 along with shaft 171., the wheel willalways maintain its engagement with the rack. The dab 170 is thereforeby the sliding movement of fork 178 oscillated above gluing roller 166,and is then, by the turning of the angle lever 173, lowered upon thebottom, flap of the box cover, to be again raised and moved outwardly.Plate 158 is now raised by the rack 162, so that the bottom flap ispressed against the previously closed three cover flaps and glued to thesame. The table 116 will then again turn 90, during which movement thatpart of the box that projects beyond casing-115, will be caused tostrike a curved abutment 181, for the pur= pose of pressing the coverfiapstightly together and thus effect their intimate union. After therotation of the table as described,

' the casing 115 with the closed box will face a stripper 183 carriedbythe long arm 182 of a rotatable shaft 184. The latter is provided with acrank 185 having a roller 186 that engages a cam 187, by the rotation ofwhich arm 182 is swung to cause stripper 183, to enter a slit 184 ofcasing 115 and thuspress the box out of the casing. The box will bereceived upon a plate 189 turning on pivot 188, and jointed to a rod190, which is operated from shaft 87, by means of a roller and cam (notshown). When plate 189 is raised, the box supported there by is byoscillative arms 191 tilted off the same and upon a conveyer belt 192,where the box arrives in such a position that one of its heads will restupon the same. Arms 191 are fast on a shaft 194 journaled in a bearing193 and carrying a slotted lever 195, which by. pin 196 is connected toa slidable rod 197. The latter is operated from shaft 87 by a cam androller (not,shown).

Above conveyer belt 192 running over pulley 198, is arranged a secondconveyor belt 199 running over pulley 200 and mov-- ing'with a likespeed.' The two conveyers move with their opposed faces in the samedirection, 2'. e. away from the "machine. The box tipped upon the lowerbelt 192, is thus drawn by the same underneath the upper belt, and isthus carried off by both belts. During. this movement the lower beltwill press against the flaps of one box head, while the upper belt willpress against the flaps of the other box head, so that the same are notliable to spring open, and that the box when leaving the conveyers isperfectly dry and securely closed.
